Greetings,
We are planning to use camunda community for our BPM offering. We are using camunda as sharable on tomcat install. While going thru links have couple of questions related to version upgrade.
#1 We are planning to use 7.14. In future if we got another version(7.15 or)
a) Is it sufficient to upgrade camunda engine jar,webapps,rest war?
b) Will there be any impact to running requests or process. Any alterations needed at DB?
#2 For enterprise edition , I saw in a link there will be quarterly patch releases. Will those/some of patch features will be included in next community version upgrades?
No - you’d also need to update the database. you can find detailed documentation on how to upgrade from one version to another right here.
There doesn’t have to be - we’ve ensured that it’s possible to do a rolling upgrade to the latest version, so if you’ve got a cluster of camunda instances running it’s quite easy to update one at a time without any downtime or any interruptions to running instances. Take a look here for more details.
Patch releases for the Enterprise version can be more frequent than just quarterly, especially security patches, we release those to our enterprise customers as soon as any security issues are found. The open source version is released every 6 months. All patches created during the 6 months release cycle are added to the open source version when it’s released.
This means that if there is a bug or a security issue with the current version of the open source version the maximum amount of time you’d need to wait until you get the fix is a little less than 6 months.
